Characteristics of Heat Mode
The system automatically controls the following operating modes to prevent the reduction of heating
capacity and space comfort.

●
and loss of heating capacity.
The indoor unit fan will stop, and “
●
STANDBY
” (Defrost/Hot start) will be displayed on the remote controller.
The system will return to normal operation usually within six to eight minutes (but not more than
●
10 minutes).
Hot start
When the system goes into heat mode, the indoor unit fan will stop in order to prevent a cold draft.
●
(In that case, “
STANDBY
” (Defrost/Hot start) will be displayed on the remote controller.)
Dry Mode
Preparation
For equipment protection purposes, apply power to the outdoor units at least six hours before starting the operation of the system.
●
The dry mode may not be selected if the remote controller is master controlled and the system is not already in the cooling mode of
●
operation. (see page 15 for details)
In case of changing the operation mode by the Cool/Heat Selector, set it to cooling operation mode.
